The Guy who stars in most of the still frame shots on this video and who made it, is a gentleman by the name of Paul Genge. He contributed to the Mega thread 'Final report: Systema.'. His reputation on this board is pretty shocking, after the debacle surrounding the video he made, with a guy named Ritchie Grannon. As detailed in the thread, Ritchie was initially impressed with what Genge had to say and with the system. But later, for reasons that escape me now, went back on his association with Genge.
Although he remains somewhat impressed by what the system had to offer. He also remains, utterly unimpressed with Genge.

Again, wish i could remember what happened. I do know that Grannon wants the systema Q&A vid removed from Youtube but Genge has yet to comply.

I believe the guy your talking about is Paul Genge. Not knowing much about him I went to his schools website and apparently he studied Bujinkan Taijitsu [yes, the definition of bullshido] for years until 2000 when he went to Toronto Canada to study Systema for 6 weeks. Apparently this was enough experience in the system for him to start teaching. My source is sited below.

I'm trying to find the video of Paul having a sparring session with some sort of boxer/kickboxer/mma guy. It's a minute or two long, and shot in black and white I believe... this is not the video of the supposed MMA British guy who "pressure tests" Systema and looks awful in doing so. If anyone has a link to the video I'm talking about please post it.
